WEIGHING APPARATUS FOR REFRIGERATORS.

Specification of Letters Patent.

Patented A nea, 1912.

Application filed October 23, 1911. Serial No; 656,344.

To all whom it may concern:

Be it known that I, FRANK B. HARRING- TON, a citizen of the United States, and a resident of Elk City, in the county of Beckfor attaching it to, and supporting .it upon,

the inner walls ofthe receptacle.

The details of construction, arrangement, and operation are as hereinafter described, and illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the apparatus, together with a vertical section of cillate on the a portion of a refrigerator wall. Fig. 2 is a front view of a portion of the refrigerator. Fig. 3 is a perspective view illustrating one of the fulcrums of the rock shafts forming part of the apparatus. a

, In Fig. 1, A indicates a horizontal icerack or pansupported by four vertical rods B from the lugs or short arms C of parallel rock-shafts D, which are arranged over the pan and fulcrumed .on brackets E that are fixed to the wall of the 'refrig'erator. The fulcrums proper are lugs (1 formed on the rock-shafts andresting and adapted to osbracket shoulders esee especially Fig. 3. Practically these lugs serve the purpose of the ordinary or well known knife-edges with which scale levers are commonly provided. The rock-shafts D are further provided with long radial lever arms F whose inner adjacent ends are connected, by push-rods G, with an indicator beam H whichis arranged below the shafts, but near and over one side of the pan A, and is fulcrumed'at I on a bracket which is, in practice, screwed to the refrigerator wall. The other or free end of the lever H is suspended by a spiral spring J from one arm of-a pivoted elbow lever K, whose other arm is connected'by a swiveled stirrup with an adjusting screw M that passes through.

the refrigerator wall N and also through a metal plate 0 atfixed to the outer side of the wall, as shown, By rotating the screw M, it is apparent that the elbow lever and spring may be adjusted if required to raise the free end of the indicating lever H in order to cause the index to point exactly to zero on the graduated scale. The free end of the beam H is further connected by a rod P with a small rock-shaft to which an index or finger Q is rotatably applied and adapted to sweep 0"61 a graduated are R. In practice, the latter is arranged on the outer side of a refrigerator, as shown in Fig. 2, and is covered and rotected by a glass plate S.

From the oregoing description, it will be apparent that ice or other articles to be weighed, upon being placed upon the rack or pan. A, will depress the latter correspond,-

ing to their weight, and thus, through the medium of the rockshafts, their lever arms, and push-rods G, the indicating lever H will be depressed correspondingly against the resistance of the spring J, and the index or movable pointer will move over the are R to a point indicating thereon the weight in pounds and ounces of the article in the pan.

Thus constructed and applied, the apparatus occupies comparatively small space in the refrigerator or other receptacle in which it may be employed and furnishes a most convenient and speedy means for ascertaining the weight of any article that is to bedeposited in the receptacle. "The apparatus may be applied in refrigerators and iceboxes already constructed, as well as in receptacles specially constructed to accommodate it.

I do not desire to be understood as confining myself to the details or specific features of construction and arrangement of parts, since such changes and modifications may be made in practice as fairly fall within the scope of my invention.

What I claim is 1. The apparatus adapted for the use specified, comprising a pan, parallel rockshafts arranged over the pan, and means for suspending the latter therefrom, an inport and on which the 10ckshafts are supsuhp0rtinl and adjusting the spring vertiported rotatably, lever arms projecting incally, as s own and described. Ward from the rock-shafts, an indicating 1ever pivoted on a fixed fulcrum below the FRANK HARRINGTON 6 rock-shafts, and push-rods connecting the \Vitncsses: same with the lever arms, a spring support BENJAMIN R. LEWIS,

for the free end of the lever, and means for LEWIS F. SIGLIN.
